Figs. 35, 36, 37, 38, 39 and 40 present one more form in which myinvention is embodied, and

Fig. 41 shows a further embodiment of the invention.

On the drawings the same numerals identi the same parts throughout.

eferring first to Figures 1 and 2, the upper part of a body of acollapsible tubular container for tooth paste or the like is indicatedat 1. It has a conical upper end 2 provided with a central threadedoutlet neck 3 for the usual screw cap which closes the tube, a bead 4may encircle the circumference of the conical end 2. This beadreinforces the tube'and makes it hard and rigid around the edge at theend 2. The numeral 5 indicates a resilient clam ing elementapproximately semicircular an shaped to grip the tube 1 around the end2. ,This clamp may have a portion which engages the body 1 adjacent thebead 4; and be grooved inside to receive the head 4; and have its upperedge turned over at 6 to rest upon the tube 2. To this clamp is secureda protecting or covering mam er in the form of a relatively large cap 7;the connection being provided by means of a hinge 8; and the cap has anextension 9 to which is pivotally connected an operating member 10 havinone end which is bent up The hinge 8 may be a spring hin e to keep thecap 7 normally covering the nec 3 and to lift the cap one merely pullsthe member 10 down with the finger.

.In Fig. 3 the rotecting member is in the form of a flat p ate 12 whichfolds over the end of the neck and is bent and connected to the clamp 5in the same way.

Fig. 4 shows the attachment of Fig. 1 with the clamp 5 provided with anextension 5 running down along the side of the tube and the operatingmember 10 has a projection 10 to engage and book under a similarprojection 5 of extension 5*. By bringing these two projections intoengagement the cap can be held in resting position, as indicated in Fi5.

igs. 6 and 7 show the tube having a protecting member consisting of acap 13 which has a. central opening 14 which registers with the openingin the outlet neck 3. This member 13 is dome sha ed and its lower edgesturn outwardly slig tly to rest upon the conical end 2 of the tube 1. Itis held in place means of a clamping rin 15 which encircles the end ofthe tube; this ring engaging the body 1 and being internally grooved toreceive the bead 4 and having a portion6 which is conical and overlapsand engages if the lower edge of the member 13 to hold it in place. Thisring may be a split ring to be more readily put into position.

In this form and all other forms of my invention the device is securedto the tube by engaging with sufficient firmness the rigid part of thetube aflorded by the bead 4.

Fi s. 8 and 9 show a similar protecting mem er 13 with a central opening14 as before and the lower end of this member 13 is provided with lugs18 which can be bent under the bead 4 to hold the member in place.

Fig. 10 shows a dome shaped member 13", the lower end of which is beadedso that it canfit upon the head 4 and this beaded lower edge is cut asindicated at 16 to enable the edge to yield to a sufficient extent topermit it to he slipped over the head 4 when the L member is being puton the tube. As soon as the cut or split lower edge passes the bead theresiliency of the portions thereof between the cuts causes this edge togrip the bead and hold the member firmly on the tube.

Referring to Figs. 11, 12, 13 and 14 I show i 23 carried by one of theother pair of ends 20; so that when this other pair of ends 20 isbrought into proximity with each other and secured by the clasp 23 thetwo arms 19 will encircle the upper end of the tube just below the bead4 with sufficient tightness to enable any kind of a protecting cover tobe mounted on this tube. i The shield of Figure 8 can advantageously beused with the device of Figures 11 and 14, by bending the tabs or lugsunder the arms 19. The lugs will then hold better than if bent againstthe tube under the bead 4.

In Figs. 15, 16 and 17 are shown a mounting device for attaching aprotecting member to a collapsible tube comprising semicircular arms asbefore, the ends of which are bent as at 24, these ends being made tocross each other so as to be hinged together as at 25. This mounting isput on a collapsible tubular container by pulling the arms away fromeach other as shown by the broken lines in Fig. 16. It is then slippedon the end of a tube and the arms moved together and so held by means ofcatches or clasps 23. These clasps are provided for each pair of arms24, one of these clasps being mounted upon one arm of each pair toengage and hold the other arm of said pair and keep the mounting in '27secured by a hinge 29. The disc 27 also carries a spring catch 30 toengage a projection 31 on the cap and hold it closed.

ms-4e Figs. 20, 21 and 22 indicate a mounting similar to thatof Figs.and 17, comp'risii'i'g semicircular arms 19, the downturned ends otwhichare hinged together as before but the arms 19 may be below the bead 4 ofthe tube and on top of each arm is the semicircular half of a conicalring 26; this mounting is put on the end of a tube by pulling the arms19 and the two semicircular halves of ring 26 apart as shown in brokenlines of Fig. 21. IVhen the arms are moved together and secured by thecatches 23 the two halves of the ring will rest'upon the conical top 2of the tube, and the arms 19 will engage the undersid-e of the bead.

Figs. 23, 24 and 25 show a mounting for a protective covering to beutilized on the end of a collapsible tubular container which consists ofa pair of arms 19 with down turned ends 24 similar to'wliat appears inFigs. 16 and 21 and with catches 23 Secured to the ends 24 of each'arm19 and below the same is a semicircular arm 32, a space beingprovided between the arms 19 and 32 of each half of this device. Whenthis device is put into place the arms 19 will be above the bead 4 ofthe tube 1 and the arms 32 below the bead so that the device cannot beslipped off.

Figs. 26, 27 and 28 illustrate a mounting device consisting of arms 19of semicircular form with down turned ends 24 hinged together andprovided with catches 23 Instead of the arms 24 being made to cross eachother as in Fig. 24, for example, one of these ends has aprojection 24to which the adjacent endot the other arm is pivoted. The arms 19encircle the tube below the bead 4 and hinged to one of the arms is aprotective covering 33 having a dome shaped top 34 and a flaring loweredge 35 which rests upon the two curvedsemi'circular arms 19. It may beconnectedto one of these arms by a spring hinge 36 and be provided witha knob 37 to be pressed down to lift the cover 33.

I In Figs. 29, 30 and 31 the tube 1 has a'member 38 which rests upon theconvex top 2 and has a neck39 with an opening 40 which receives the neck3. Upon this member 38 is hinged a cover 41 by means of a spring hinge42 and this cover has a projection 43 to be en gaged and held down by aspring catch 44 secured to the edge of the member 38. The member 38 hasa down turned edge 45 which slips over the bead 4 and to keep thisattachment from'coming OK the top of the tube I provide a retainingelement 46 consisting of a piece of wire bent to provide parallelportions 47, the ends of which are secured to an are shaped bar 48. Thisbar is mounted in a bearing 49 made integral with the edge 45 of themember 38. The central part of this bar may be on the outside of theedge 45 and this edge may have recesses to permit the ends of the bar topass between this edge 45 and body of the container 1. The two portions47 neck holds the member 68.

afford a hold for a the operators fingers. hen the attachment is put onthe tube the retaining element will have the position shown in brokenlines in Fig. 29. By pressing down upon the two parallel portions 47 thebar 48 swings upward into the notches 50 and is pressed tightly betweenthe body 1 of thetube and the edge 45 so as to keep the attachment frombeing pulled cit. The bar presses against the body of the tube adjacentthe rigid bead 4, and against the underside of the bead. To remove theattachment the retaining element is actuated by taking hold of portions47 and pulling them upward. The edge 45 may have spring portions 51which grip the ends of the bar 48 and'hold this bar releasably in place.

In Figs. 32, 33 and 34 the attachment consists oi a pair of clampingelements 52, the ends of which are separated, each comprising a portion53 to engage the body 1, a hollow bead 54 to receive the bead 4 of thecontainer and a conical edge 55 to rest upon the conical end 2 of thetube. These elements 52 are connected by means of resilient arms 56 to aring 57. To put the attachment in place the end of the tube 1 carryingthe end 3 is simply pushed through the ring 52 until the head 4 fitsinto the hollow bead 54 of the two elements 52 which yield to the extentrequired to receive the bead 4. Then the end of the tube is covered by amember 58 which fits upon the conical end 2 and has a neck 59 whichcovers the end of the neck 3. The member 58 may have a cylindrical edgewhich grips and its tightly around the hollow bead 54 so that the member58 will not come ofl.

By outlet end of the tube, is meant that portion which is usually maderigid and is o f more or less conical shape and has an outlet neck ornozzle which is usually screw threaded. The detachable devicesdescribed, each attach to some portion of this outlet end and to therigid portion thereof. In Figures 11 and 12 for instance the portion 19compresses the fiexible part of the tube and also abuts tightly againstthe rigid bead of the outlet portion. In Figs. 29 and 30 for instance,the portion 48 engages the flexible portion and abuts against the rigidoutlet end.

In Figs. 3540, the conical top is covered with a conical member 58, asin Figs. 2931, having a neck 59 with opening 40 and to this member aresecured curved clamping arms 61,

pivoted at 62, with a catch 63 on one arm to engage a stop 64 on theother. To one ring oted at 66 to swing sidewise and downward and'exp'osethe opening 40. V

In Fig. 41, I show a conical member 68 fitting against the top 2, andallowing the neck 3 to project through it. A nut 67 on the On thismember mounted'th'e cap 7, pivoted'by a hinge at iii;

8, with an extension 9 on the hinge to which 1711! is attached a member10, with out-turned end 11 for the finger to pull down. The member 68has an extension 5, with a projection 5" to. engage a projection 10 onthe part 10,

when the latter is pulled down to hold the cap in raised position. Thenut 67 may be counter sunk on its lower face to fit snugly down on theupper end of the member 68, as shown in dotted lines on Fig. 41.
